4) Open the Registry Editor, regedit.exe.
5) Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\AutoMate\Automate Agent 11\TaskService\Agent.
6) In the right hand box, right click in the white space and New/String Value, and name it RegistrationUsername, then set it's value to administrator.
7) Repeat the above step again, however user the name RegistrationPassword and set the value to the Automate Enterprise administrator user's password, defaults to password.
